USB Loader GX and WiiFlow Problems

Wii 4.3E, used Bathaxx. Installed d2x v9 CiOS 249/50.

Ok, I soft modded a Wii for the neighbour, they are very computer illiterate so I'm trying to keep loaders as simple as possible for them.

I thought, Wiiflow is the most simple straight forward loader so I installed that as a forwarder but the problem I'm having is when I click to play a game, I get a black screen. It worked once before from a USB.

USB Loader GX freezes on 'Initializing USB Device', but works if I unplug it and wait till it says to plug the USB in.

Once I plug it in everything works fine, but I can't be having to keep unplugging and plugging the HDD in.

I'm copying the games to my computer now and going to format the external hard drive then retry.
